Swapping ETH to BTC is one of the most liquid pairs in crypto, often used to consolidate gains from DeFi or NFT activity into a long-term store of value. Without KYC, you skip account creation, identity uploads, and withdrawal holds - the swap settles directly to your BTC address. This page pulls live quotes from 17 non-custodial aggregators so you can see real receive amounts after fees, not advertised rates.
Why ETH -> BTC is a special case
ETH and BTC sit on entirely separate chains with no native bridge, so every swap requires a counterparty or liquidity pool willing to take ETH on Ethereum and release BTC on Bitcoin's mainchain. This is the deepest non-stablecoin pair in crypto, which means tight spreads (typically 0.1-0.5 percent on top of mid-market) and minimal slippage even on five-figure tickets. Confirmation timing is asymmetric: your ETH side lands in 1-3 minutes after 12-30 block confirmations, but the BTC payout waits on Bitcoin blocks - expect 10-40 minutes end-to-end.
Fee dynamics matter here. ETH gas at the send step can swing the effective rate by 0.5-2 percent on small swaps, so sizing up reduces relative cost. On the BTC receive side, the service pays the miner fee out of your output, and during mempool congestion that bite grows.
What to check before clicking swap
- Network selection: send native ETH on Ethereum mainnet, not an L2 or wrapped variant, unless the quote explicitly supports Arbitrum, Base, or Optimism. Sending ERC-20 WETH or L2 ETH to a mainnet-only deposit address is the most common way funds get stuck.
- Receive address: use a native SegWit (bc1q) or Taproot (bc1p) BTC address to minimize the withdrawal fee deducted from your output.
- Rate type: floating rates give you the market price at execution but expose you to drift during confirmations; fixed rates lock the quote but charge a 0.5-1 percent premium and often have tighter min/max bounds.
- Refund address: always provide one. If the deposit arrives outside the quoted window or below the minimum, this is the only way funds return.
Practical tip: avoid swapping during high-gas periods (US market open, major NFT mints) - waiting for gas to drop below 20 gwei can save more than shopping for a better rate.
Frequently Asked Questions
How long does an ETH to BTC swap take end-to-end?
Typically 15-40 minutes. Ethereum needs 12-30 confirmations (roughly 3-7 minutes) before the service releases BTC, then Bitcoin needs 1-3 confirmations on the receive side (10-30 minutes depending on fee bid and mempool state). Fixed-rate swaps may be faster because some services credit after fewer ETH confirmations.
Can I send ETH from Arbitrum or Base instead of mainnet?
Only if the specific quote lists that L2 as a supported deposit network. Most aggregator routes assume Ethereum mainnet. Sending L2 ETH to a mainnet address will lose the funds. If you hold ETH on an L2, either bridge to mainnet first or filter for services that accept Arbitrum/Optimism/Base deposits directly.
Why does the rate I see differ from Coinbase or Binance spot?
Aggregator quotes already bake in the service spread (0.1-0.5 percent), the BTC network fee deducted from your output, and sometimes a buffer for ETH gas volatility. Centralized spot prices are mid-market without these costs. Compare 'you receive' amounts across services rather than headline rates.
What is the minimum ETH amount that makes this swap worthwhile?
Most services set minimums around 0.01-0.02 ETH, but economically the floor is higher. Below roughly 0.05 ETH, combined gas plus BTC withdrawal fees can eat 3-5 percent of the swap. For amounts under 0.1 ETH, batching or waiting for low-gas windows materially improves your output.
Is a fixed rate or floating rate better for ETH to BTC?
Floating wins on average for this pair because ETH/BTC is liquid and stable minute-to-minute, so drift during confirmations is usually small. Choose fixed if you are swapping a large amount, if BTC or ETH is moving more than 1 percent per hour, or if you want exact accounting for tax purposes.
What happens if I send the wrong amount or miss the deposit window?
If you provided a refund address, the service returns ETH to it minus network fees. Without a refund address, recovery depends on the operator and can take days or fail entirely. Always copy the refund field before sending, and double-check the deposit min/max - sending 0.5 ETH to a quote capped at 0.4 will trigger a refund or manual review.
